Teaching MPPSC Assistant Professor Mock Test Series 2025 Physics Work Power and Energy Potential Energy Curve
The potential energy of a particle moving along x-axis varies as
U(x) = \(-\frac{x^4}{4} + 2x^3-\frac{11x^2}{2} + 6x + 23\)
Where U is in Joule and x is in meter. The correct option regarding the stable, unstable, and neutral equilibrium of the particle is -
1
It is at unstable equilibrium at x = 1 and x = 3 and at stable equilibrium at x = 2.
2
It is at stable equilibrium at x = 1 and x = 3 and neutral at x = 2
3
It is at stable equilibrium at x = 1 and x = 3 and at unstable equilibrium at x = 2.
4
It is at neutral equilibrium at x = 2, unstable at x = 1 and stable at x = 3
